Systems and methods for generating technical documentation from enterprise service-oriented architecture content

ABSTRACT

Systems and methods are provided for generating technical documentation from content, such as enterprise SOA content. In one implementation, a computer-implemented method is provided that comprises receiving an identifier of a service interface description that defines an interface for implementing a service and processing one or more packages associated with the service interface description by reading data from one or more files of enterprise SOA content stored in a database. In addition, the method generates the technical documentation using the data read from the one or more files.

BACKGROUND

I. Technical Field

The present invention generally relates to the field of data processingand to systems and methods for generating technical documentation. Moreparticularly, the invention relates to computerized systems and methodsfor generating technical documentation from, for example, enterpriseservice-oriented architecture (SOA) content.

II. Background Information

In an enterprise, the term “service-oriented architecture” (SOA) refersto an architecture that provides a collection of services that maycommunicate with each other. A “service” is a programmable,self-contained, self-describing, modular application function that canbe published, discovered, or invoked through an open Internet standard.Each service is typically self-contained and the services are madeavailable to users in the enterprise via a distributed systemarchitecture. The services may be, for example, Web based and availableover Internet protocols. Furthermore, the services that are provided inan enterprise SOA are typically defined in a standardized, but technicalmanner. That is, the services are defined using a particular programminglanguage, such as the Web-Service Definition Language (WSDL). WSDL is anXML format that describes services as a set of endpoints operating onmessages containing either document-oriented or procedure-orientedinformation.

In languages such as WSDL, the operations and messages are describedabstractly, and then bound to a concrete network protocol and messageformat to define an endpoint. Related concrete endpoints are combinedinto abstract endpoints (i.e., the “services”). WSDL is extensible inorder to provide a description of endpoints and their messagesregardless of what message formats or network protocols are used tocommunicate. Accordingly, WSDL is an example of a XML (eXtensible MarkupLanguage) Service Definition (XSD) format.

Using the WSDL language to define services provides a powerful andeffective tool. However, the WSDL language is not easily readable byhumans. As a result, programmers must prepare technical documentation inorder to describe and explain the service interfaces to otherprogrammers. An enterprise might prepare technical documentation usingword processing software (e.g., Microsoft Word documents), spreadsheets(e.g., Microsoft Excel sheets), or flow diagrams (e.g., Visio files),for example. The process of generating the documentation is timeconsuming because the documentation is prepared from scratch. Moreover,since services may evolve over time, programmers must update thedocumentation because, in order for programmers to easily understand andefficiently update content, documentation is needed that accuratelyreflects the current content that is being used by an enterprise.

Furthermore, when building enterprise SOA services, the services must bestandardized. To maintain consistency between services, the technicaldocumentation must be updated regularly when requirements change and aservice is updated. Services must also be controlled such that servicesare not made available until proper technical documentation has beenprepared. For example, an enterprise that stores content in anEnterprise Service Repository (ESR) might require technicaldocumentation in multiple formats (e.g., Word, Excel, and Visio) to beprepared for each service before it can be implemented in the ESR.Often, since the technical documentation is prepared in multipleformats, the documentation contains redundant data. Moreover, manuallypreparing and continually updating the technical documentation is a timeconsuming and error-prone process.

Therefore, conventional techniques for manually preparing and updatingtechnical documentation suffer from one or more drawbacks, such as thosehighlighted above. In view of the foregoing, there is a need forimproved systems and methods for automatically generating technicaldocumentation from enterprise SOA content.

DESCRIPTION OF THE EMBODIMENTS

The following detailed description refers to the accompanying drawings.Wherever possible, the same reference numbers are used in the drawingsand the following description to refer to the same or similar parts.While several exemplary embodiments and features of the invention aredescribed herein, modifications, adaptations and other implementationsare possible, without departing from the spirit and scope of theinvention. For example, substitutions, additions or modifications may bemade to the components illustrated in the drawings, and the exemplarymethods described herein may be modified by substituting, reordering, oradding steps to the disclosed methods. Accordingly, the followingdetailed description does not limit the invention. Instead, the properscope of the invention is defined by the appended claims.

Systems and methods consistent with the present invention providecomputerized systems and methods for generating technical documentationfrom enterprise service-oriented architecture (SOA) content. As usedherein, the term “content” shall include enterprise services, programcode, and/or other data, which may be stored in a repository. Forexample, content may be stored in the repository in an XML ServiceDefinition (XSD) format, such as Web-Service Definition Language (WSDL).Additionally, interfaces for implementing services may be stored in therepository in an XSD format.

Embodiments consistent with the present invention provide systems andmethods for generating technical documentation using, for example, anXSD description of a service. Systems and methods disclosed hereingenerate technical documentation automatically by reading content, suchas an XSD description of a service, and converting the content into userreadable files. The user readable files may be, for example, MicrosoftOffice files, such as Word, Excel, and Visio file formats. Disclosedembodiments allow programmers to create enterprise SOA content and thenautomatically generate technical documentation for the content.Accordingly, programmers do not need to manually create or updatetechnical documentation for enterprise SOA content due to design changesand software updates.

FIG. 1 illustrates an exemplary system 100 for generating technicaldocumentation from enterprise SOA content, consistent with an embodimentof the present invention. As shown in system 100, application server110, repository server 120, documentation server 130, and terminals 140,150, and 160 are connected to a network 170. One of skill in the artwill appreciate that although three kinds of servers and three terminalsare depicted in FIG. 1, any number of servers and terminals may beprovided. Furthermore, one of ordinary skill in the art will recognizethat functions provided by one or more components of system 100 may becombined. For example, application server 110 and repository server 120may be implemented as one server.

Network 170 provides communications between the various entities insystem 100, such as application server 110, repository server 120,documentation server 130, and terminals 140-160. In addition,application server 110, repository server 120, documentation server 130,and/or terminals 140-160 may access legacy systems and/or databases (notshown) via network 170, or may directly access legacy systems and/ordatabases. Network 170 may comprise any suitable combination of ashared, public, and/or private networks and may encompass a wide area orlocal area. For example, network 170 may be implemented through anysuitable combination of wired and/or wireless communication networks.Furthermore, network 170 may comprise a local area network (LAN), a widearea network (WAN), an intranet, and/or the Internet.

Application server 110 may comprise a general purpose computer (e.g., apersonal computer, network computer, server, or mainframe computer)having a processor (not shown) that may be selectively activated orreconfigured by a computer program. Application server 110 may interfacewith repository server 120, documentation server 130, and/or terminals140-160. Furthermore, application server 110 may distribute content toterminals 140-160. For example, application server 110 may retrievecontent from repository server 120 for transmission over network 170 toterminals 140-160.

Repository server 120 may include a database 122. Database 122 may beimplemented using one or more of a number of commercially availablerepositories. However, in a preferred embodiment, the EnterpriseServices Repository from SAP AG (Walldorf, Germany) is used.Furthermore, repository server 120 may employ any of a number ofcommercially available database systems, such as Microsoft Access,dbase, Oracle, Sybase, etc. Database 122 may also store definitions ofinterfaces that implement services. In one embodiment, interfaces arestored in an XSD format. However, other embodiments of the presentinvention may store interfaces in any other appropriate format.

Interfaces are made up of one or more “service interface descriptions.”In turn, service interface descriptions include data types. Serviceinterface descriptions and data types may be stored in an XSD format,for example. An example of a data type is “address.” The “address” datatype can be used in one or more service interface descriptions. Forexample, “address” may be used by a service interface description“Create PO” and a service interface description “Create Invoice.” In thefollowing discussion, the term “service interface description” refers toan interface structure. Furthermore, a service interface description maydefine the structure of an interface stored in database 112. Forexample, a “service interface description” may be called a “message datatype,” as used in the Enterprise Service Repository, available from SAPAG of Walldorf, Germany.

Data types that are included in a message data may have different levelsof complexity. For example, at a basic level, one data type that may bedefined for a service interface description is an “element.” Examples ofelements that may be provided as a basic level of a data type include,for instance, the data type “address.” Database 112 may also storeadditional information for a service interface description, such asinformation defining “entities” included in a service interfacedescription. “Entities” refer to structural elements of a serviceinterface description. For example, the data types “Create PO” and“Create Invoice” may be implemented as entities. Database 112 may alsostore additional structuring information, such as information defining“packages.” “Packages” refer to groupings of more than one entity.Furthermore, database 112 may store information identifying whichentities and elements belong to which package. Accordingly, database 112may store service interface descriptions, as well as informationdefining elements, entities, and packages that may be associated with aparticular service interface description.

Repository server 120 may be available via network 170 and may interactwith software executing on application server 110 and/or or withsoftware executing on terminals 140-160. For example, content stored indatabase 122 may be accessed by application server 110 and/or terminals140-160. Furthermore, content may be retrieved from database 122 andtransmitted over network 170 to one or more of terminals 140-160 at thedirection of application server 110, for example.

Collectively, application server 110 and repository server 120 mayimplement an exchange infrastructure. In one embodiment, applicationserver 110 and repository server 120 may constitute an exchangeinfrastructure (XI) system, such as a SAP XI system. An XI system mayprovide a collection of services that are available to an enterprise.Details of an exemplary XI system are provided in PCT InternationalPublication Number WO 2003/083600 A2, filed Oct. 9, 2003, which ishereby incorporated by reference in its entirety.

In operation, documentation server 130 may generate technicaldocumentation from content that is stored in repository server 120. Inone embodiment, documentation server 130 may directly generate technicaldocumentation in a standard format, such as hypertext markup language(HTML) or unified modeling language (UML), which can later be importedby one or more applications such as Microsoft Office applications, forexample. In another embodiment, documentation server 130 may interactwith one or more applications via application programming interfaces(APIs) in order to create files such as Microsoft Excel sheets orMicrosoft Word documents, for example. APIs to Microsoft Officeapplications may enable documentation server 130 to generate files of aspecific format. In one embodiment, APIs may be stored in documentationserver 130. In yet another embodiment, documentation server 130 maygenerate Microsoft Office and/or other files from HTML or UML files thatwere previously generated.

Terminals 140-160 may be any type device for communicating withapplication server 110 and/or repository server 120 over network 170.For example, terminals 140-160 may be personal computers, handhelddevices, and/or any other appropriate computing platform or devicecapable of exchanging data with network 170. Terminals 140-160 may eachinclude a processor (not shown) and data storage (not shown) for storingdata. For example, terminals 140-160 may execute program modules thatprovide one or more graphical user interfaces (GUIs) for interactingwith network resources in order to access one or more services providedby application server 110 and repository server 120. Users of terminals140-160 may access services via network 170 through a web browser orsoftware application running on, for example, any one of terminals140-160.

FIG. 2 is a flow diagram 200 of an exemplary method for generatingtechnical documentation from enterprise SOA content, consistent with anembodiment of the present invention. In particular, FIG. 2 provides anoverview of a method for generating technical documentation withdocumentation server 130. For example, documentation server 130 maygenerate technical documentation for content stored in repository server120 in one or more formats.

At the start of the process, in step 210, documentation server 130receives an identifier (e.g., a name) of a service interface descriptionfor which the documentation should be generated. The identifier for theservice interface description may be specified by a user at one ofterminals 140-160, for example. Alternatively, in order to keeptechnical documentation up to date, documentation server 130 mayautomatically update technical documentation according to apredetermined schedule (e.g., hourly, daily, monthly, etc). For example,technical documentation may be kept up to date for one or more serviceinterface descriptions by automatically updating the documentation whenspecific events or times occur.

In step 220, documentation server 130 generates technical documentationfor the received service interface description identifier. For example,during step 220, documentation server 130 may generate an introductionfor the document, as well as sections corresponding to elements,entities, and packages of a particular service interface description.Furthermore, documentation server 130 may directly generate technicaldocumentation in a standard format, such as hypertext markup language(HTML) or unified modelling language (UML), which can later be importedby one or more applications such as Microsoft Office applications, forexample. In another embodiment, documentation server 130 may interactwith one or more applications via application programming interfaces(APIs) in order to create files such as Microsoft Excel sheets or Worddocuments, for example. In yet another embodiment, documentation server130 may generate Microsoft Office files from HTML or UML files that werepreviously generated. Further details and embodiments concerninggenerating technical documentation are provided below.

In step 230, documentation server 130 may store the generated technicaldocumentation and/or may transmit the generated technical documentationover network 170 to, for example, application server 110 and/orterminals 140-160. The generated technical documentation may be in astandard format, such as HTL or UML, or may be in a commerciallyavailable format, such as Microsoft Office format.

To generate technical documentation (step 220), documentation server 130may execute one or more program modules corresponding to the above-notedfunctions and sub-functions. For example, documentation server 130 maygenerate an introduction for the technical documentation and thenprocess one or more packages. For each package, documentation server 130may generate a package chapter and a package definition. Furthermore,during execution, documentation server 130 may interface with database122 of repository server 120.

Consistent with embodiments of the invention, documentation server 130may also obtain and process the entities for each package and anysub-packages. For each entity, documentation server 130 may generate anentity chapter, entity definition, and an entity structure.Documentation server 130 may also obtain and process the elements foreach entity. That is, for each element, documentation server 130 maycreate an element chapter and an element definition, as well as processany sub-entities. One of ordinary skill in the art will appreciate thatone or more data types may be omitted in certain embodiments of thepresent invention, depending upon the complexity of a particular serviceinterface description.

For purposes of illustration, the following is a listing of exemplarypseudo code that outlines the processing that may be performed bydocumentation server 130 to generate technical documentation for aservice interface description:

  main( ) { write introduction( ) process_packages(root_package)extract_GDTs( ) } process packages(packages) { LOOP AT packages INTOpackage.   create package chapter(package)   create packagedefinition(package).   entities = get entities(package).   processentities(entities)   subpackages = get subpackages(package).   processpackages(subpackages). ENDLOOP. } process entities(entities) { LOOP ATentities INTO entity.   create entity chapter (entity)   create entitydefinition(entity).   create entity structure(entity).   elements = getelements(entity).   LOOP AT elements INTO element.     create elementchapter(element)     create element definition(element).    occurrence(element).   ENDLOOP.   subentities = getsubentities(entity)   process entities(subentities) ENDLOOP. }

FIG. 3 is a flow diagram 300 of another exemplary method for generatingtechnical documentation, consistent with an embodiment of the presentinvention. The exemplary method of FIG. 3 may be implemented toautomatically generate technical documentation for a service interfacedescription. While the following process is described with reference togenerating a word processing document (e.g., a Microsoft Word file), theprocess may be adapted for generating other kinds of documentation, asdiscussed below in further detail.

In step 302, documentation server 130 receives an identifier of theservice interface description. Documentation server 130 may receive theidentifier of the service interface description from, for example, anyone of terminals 140-160. As discussed above, a user may requestdocumentation for a particular service interface description at one ofterminals 140-160 or, alternatively, in order to keep technicaldocumentation up to date, documentation server 130 may automaticallyupdate technical documentation according to a predetermined schedule(e.g., hourly, daily, monthly, etc).

In step 304, documentation server 130 reads information from a file(e.g., an XSD file) corresponding to the identified service interfacedescription. Documentation server 130 may read the XSD file fromdatabase 122 of repository server 120, for example, or, alternatively,from any other appropriate source over network 170. From the XSD file,documentation server 130 may create an introduction of a technicaldocument, such as a word processing document, using the definition ofthe service interface description. For example, the introduction mayindicate the service interface description and provide one or moresentences indicating that the document provides details of the serviceinterface description.

Next, in step 306, documentation server 130 generates a UML diagram fromthe interface structure and attaches it to the introduction. The processof generating a UML diagram may incorporate one or more steps discussedbelow in connection with FIG. 7 in more detail. The UML diagram may beinserted into the document as, for example, an image in any appropriateformat, such as .gif, .jpeg, etc.

Next, in step 308, documentation server 130 reads information from theXSD file to identify any packages corresponding to the service interfacedescription. As discussed above, packages may include groupings ofentities. In this step, documentation server 130 may create a chapter inthe document that corresponds to each package. For example, in a wordprocessing document, the document may include a header (e.g., of aparticular size font, in bold and/or underlined, etc.) corresponding tothe chapter. Furthermore, documentation server 130 may use the packagedefinition to create the introduction for each package chapter. That is,the package definition may be read by documentation server 310 andinserted into the document after the header for the package.Documentation server 130 may read all entities belonging to each packagefrom database 122. Furthermore, documentation server 130 may create alist of all sub packages used within a package as part of theintroduction of the package chapter and a list of all entities usedwithin a package as part of the introduction of the package chapter.

In step 310, documentation server 130 creates, within each packagechapter, one sub chapter for each entity of the package. In this step,documentation server 130 may use the definitions of entities to createthe introduction of the entity chapter. Documentation server 130 mayread all elements belonging to an entity and create, within each entitychapter, a section for each element. Furthermore, documentation server130 may retrieve from database 122, for each element, a correspondingdata type.

In step 312, documentation server 130 reads for each element thecardinality or number of occurrences of each element. For example, theelement may not be required of a particular service interfacedescription and occurs once at maximum (indicating a cardinality of anode of 0 . . . 1), the element may be required of the service interfacedescription and occurs exactly once (indicating a cardinality of 1), theelement may be optional but may occur several times (a cardinality of 0. . . n), or at least one of the element must be provided (a cardinalityof 1 . . . n). In this step, documentation server 130 may create anelement section, including the information defined the data type andoccurrence, as well as the element definitions or the data typedefinitions. Documentation server 130 may read all sub-entities beingpart of the currently processed entity and create, within the entitychapter, a chapter for each of the sub entities of the currentlyprocessed entity.

In step 314, if there are additional sub-entities, then steps 310 and312 are repeated. If there are no further sub-entities requiringprocessing, then the process proceeds to step 316.

In step 316, documentation server 130 browses the document for all datatypes being used and creates an additional chapter featuring a list ofthe data types. For example, the list may be formatted as an index ortable of contents, indicating which page or pages of the document referto particular data types. Furthermore, documentation server 130 mayeliminate duplicates such that each data type appears once in the list.

The exemplary process of FIG. 3 may be modified depending on the desiredstructure of the document or the given SOA content structure. Forexample, if packages are not used, the steps referring to packages maybe omitted. Accordingly, one of ordinary skill in the art willappreciate that modifications may be made while keeping with the spiritand scope of the present invention.

For purposes of illustration, the following is a exemplary listing of aportion of technical documentation that may be produced according to theabove-described methodology of FIG. 3:

FIG. 4 is a diagram 400 of an exemplary method for generating technicaldocumentation in a spreadsheet format, consistent with an embodiment ofthe present invention. As discussed above, the documentation may bevisualized on a spreadsheet (e.g., Microsoft Excel) in lieu of a wordprocessing document. For example, in one embodiment, an interfacestructure block may start in column m of a spreadsheet, a data typeblock may start in column p, a cardinality block may start in column q,and a package block may start in column r.

At the start of the process, in step 402, documentation server 130creates an interface structure block, which designates the structure ofthe service interface description. For example, documentation server 130may create a cell in line m and column n of the spreadsheet. In oneembodiment, the value of m should exceed r plus the number of levels ofthe service interface description to provide sufficient space to theleft of the generated structure for additional information. The value ofr may be chosen arbitrarily and specifies the horizontal position of theservice interface description representation within the spreadsheet. Thevalue of m may also be chosen arbitrarily and specifies the verticalposition of the service interface description representation within thespreadsheet. This cell is referred to in the following as a “serviceinterface description cell” and stores the name of the service interfacedescription.

In step 404, documentation server 130 identifies and reads all entitiesat the first level of the service interface description. Next, in step406, documentation server 130 inserts a line below the service interfacedescription cell for each entity. At each line, documentation server 130creates a cell in column n+1. This cell is referred to as “entity cell”and stores the entity's name. In this step, documentation server 130 mayread all sub-entities of each entity cell (e.g., column i, line j).Documentation server 130 may also create a line below line i for eachsub-entity. At each new line, documentation server 130 may create a cellin column j+1. This cell is referred to as the “entity cell” in thefollowing discussion and stores the entity's name. For all entity cells,documentation server 130 may read all elements belonging to an entity.Documentation server 130 may insert a new line below the entity cell foreach element of an entity. For example, an entity cell is located incolumn k and, accordingly, documentation server 130 creates in columnk+1 a cell in each line containing the name of the correspondingelement. This cell is referred to as the “element cell” in the followingdiscussion.

Next, in step 406, documentation server 130 creates a cardinality block.To do so, documentation server 130 may fill a cell in column q withinformation specifying the cardinality of each entity or element. Forexample, if q is chosen to be greater than m plus the number of levelsof the service interface description, none of the existing cells areoverwritten.

In step 408, documentation server 130 creates a data type block. To doso, documentation server 130 may fill a cell in column p for eachelement cell. The cell may include information specifying the data typeassociated with the element. For example, if p is chosen to be greaterq, none of the existing cells are overwritten. In this step, furthercolumns may be added to the spreadsheet, if necessary.

In step 410, documentation server 130 creates a package block. For eachentity cell or element cell that was read by documentation server 130,documentation server 130 may read the package it belongs to as well asall higher level packages of the entity or element. In this step, forexample, starting in column r, documentation server 130 may create inthe line corresponding to the cell, one cell for each package containingthe package name, starting with the top level package. These cells arereferred to as “package cells.” Furthermore, documentation server 130may fill every package cell with a color corresponding to a specificpackage. For example, certain cells sharing common or related elements,such as packages, may be coded with a common background color.Furthermore, documentation server 130 may assume that s equals thenumber of package levels in the service interface description and,accordingly, fill all cells of each line between the column containingthe outer right package cell and including column r+s with the colorcorresponding to the outer right package cell in this line.

Documentation server 130 may store the spreadsheet and/or may transmitthe spreadsheet over network 170 to, for example, application server 110and/or terminals 140-160. Furthermore, one of ordinary skill in the artwill appreciate that one or more steps may be omitted and/or substitutedfrom the foregoing discussion in accordance with a desired layout of thespreadsheet.

FIG. 5 is an exemplary spreadsheet 500, consistent with an embodiment ofthe present invention. Documentation server 130 may generate spreadsheet500 according to the exemplary method of FIG. 4, for example. Asillustrated in FIG. 5, spreadsheet 500 may include a column 502 listingpackage names, columns 504-512 including information for levels 1through 5, column 514 including the cardinality of each element, column516 including the type of each element (e.g., Message Display Tool(MDT), Global Data Type (GDT), or none), and a column 518 indicating aname or ID of each element. As also shown in FIG. 5, spreadsheet 500 maybe shaded or color coded to indicate relationships between data types.

FIG. 6 is an exemplary diagram 600 providing technical documentation,consistent with an embodiment of the present invention. Documentationserver 130 may generate diagram 600 according to method discussed inconnection with FIG. 4, for example. Although the methodology of FIG. 4was described in connection with generating a spreadsheet, the methodmay be adapted to generate a UML diagram, as shown in FIG. 6.Furthermore, a method for generating technical documentation in the formof a UML diagram is described in more detail in connection with FIG. 7.

FIG. 7 is a flow diagram 700 of an exemplary method for generatingtechnical documentation in a UML diagram format, consistent with anembodiment of the present invention. In the following, documentationserver 130 may use an API that allows for the creation and editing ofUML objects within a diagram via the API.

At the start of the process, in step 702, documentation server 130creates an UML object representing the service interface description.This object is referred to as a “service interface description UMLobject” in the following.

Next, in step 704, documentation server 130 identifies and reads allentities at a first level of the service interface description.Documentation server 130 may insert, for each entity, an UML object atthe right side of the UML object representing the service interfacedescription. This UML object is referred to as “entity UML object” inthe following discussion. The entity UML object contains the entity'sname and the UML object may be connected to the service interfacedescription object via a symbol representing an association (e.g., aline). In this step, documentation server 130 may read all sub-entitiesof each entity. Documentation server 130 may also read an entity objectfor each sub entity of a given entity and place it at the right side ofthis entity and connect it to the entity via an association symbol. Thisprocess may be repeated until no new sub-entities are found for allentities. In contrary to generating a spreadsheet, elements will. ingeneral, typically not be part of the UML diagram.

Next, in step 706, documentation server 130 creates cardinalityinformation in the UML diagram cardinality block. To do so,documentation server 130 may edit the association of an entity to itsparent entity so that it reflects the cardinality of the entity.

In step 708, documentation server 130 creates a UML object for one ormore packages present in the service interface description. A UML objectof this kind is referred to as a “package UML object” in the following.The package UML object may be considerably larger than the entity UMLobject such that a package UML object can contain one or more entity UMLobjects. Furthermore, the package UML objects may contain the name ofthe package and may be placed in the diagram such that they graphicallycomprise all entities that are part of a package and its sub-packagesand do not graphically comprise all entities that are not part of thepackage or sub-packages. In order to increase the readability of thedocumentation a package UML object can, for example, be colored in a waythat corresponds to the color used for this package in the spreadsheetrepresentation.

Documentation server 130 may store the UML and/or may transmit thespreadsheet over network 170 to, for example, application server 110and/or terminals 140-160. Also, the UML diagram may be included in thetext document, discussed above. Furthermore, one of ordinary skill inthe art will appreciate that one or more steps may be omitted and/orsubstituted from the foregoing discussion in accordance with a desiredlayout of the UML diagram.

As discussed above, documentation server 130 may generate technicaldocumentation from content that is stored in repository server 120. Forexample, documentation server 130 may directly generate technicaldocumentation in a standard format, such as hypertext markup language(HTML) or unified modeling language (UML), which can later be importedby one or more applications such as Microsoft Office applications, forexample. Documentation server 130 may also interact with one or moreapplications via application programming interfaces (APIs) in order tocreate files such as Microsoft Excel sheets or Word documents, forexample. Still further, documentation server 130 may generate MicrosoftOffice files from HTML or UML files that were previously generated.While described in connection with generating technical documentationfrom service-oriented architecture content, one of ordinary skill in theart will appreciate that the present invention may generate technicaldocumentation for other documentation, such as content stored in otherformats.
